HEATER.

Application filed September 7, 1922. Serial No. 586,608.

To all whom it may 00mm:

Be it known that I, CLIFFORD S. MAIN- CHESTER, a subject of Canada,residing at Ocean Park, in the county of Los Angeles, State ofCalifornia, have invented new and useful Improvements in Heaters, ofwhich the following is a' specification.

My invention relates primarily to a heater for use in citrus orchards,and the object thereof is to provide a heater which is simple inconstruction and which will store and hold a charge of fuel, which whenburned will burn slowly and will raise the temperature in the immediatevicinity of the heater sufficiently to prevent serious injury to thefruit on the tree near which the heater is set and will retain thetemperature above the normal temperature of the air outside theinfluence of the heater for several hours. A further object is toprovide a heater which when required for use in a citrus orchard can bequickly lighted.-

In the drawings forming a part of this application, Fig. 1 is a centralvertical section of my heater as designed for use in a citrus orchard,the fuel being omitted. Fig. 2 is a section on the line 22 of Fig. 1.

Referring to the drawings my heater consists of a starting pan 5, whichis shown as made from cast iron, but can be made of sheet metal pressedand stamped. The side walls 6 of the pan are preferably at an angle offorty-five degrees to the plane of the bottom of the pan. In the upperportion of walls 6 are draft ports 7 which are preferably equally spacedapart, and the sum of the areas of these ports is preferably equal toone fifth the area of the top plane of the outlet.

In the bot-tom of the pan is a shallow well or depression 8 for thereception of the starting fluid, not shown. Resting upon the top of thepan isthe fuel grate 9 whose bars are preferably radial. The grate isprovided with an upstanding collar 10 which at one point slopesoutwardly and forms a spout 11 which receives and guides the startingfluid into the well in the pan. Secured to collar 10 are the verticalwalls 12 preferably of sheet metal which form the combustion chamber 13.The grate, collar and walls of the combustion chamber are preferablycircular. Preferably at four equi-distant points and secured to the topof walls 12 are pockets 14 into which are recelved the legs 15 of thesheet metal deflector' 16 to hold the deflector spaced above walls 12.It will be observed by this construction that I direct the air enteringthe draft ports toward the center of the combustion chamber, therebycentralizing the flame from the starting fuel when the heater islighted. This centralization of the flame of the starting fuel insuresthe ignition of the charge of fuel in the combustion chamber with a lessamount of starting fuel than would be required if the flame were not socentralized.

Operation.

For ordinary use enough carbon briquettes or lump coal or other fuel isplaced upon the grate to burn when lighted for three hours. Thedeflector would then be positioned and the heaters set, one at each treeto be protected. When the temperature of the orchard reaches what isknown as the danger point the operatives take cans of coal oil orgasoline and pour the required %uantity into well 8 and light the same.

y the time the liquid is burned out of well 8 the fuel in the combustionchamber is lighted and continues to burn until consumed, thereby givingout suflicient heat to prevent serious damage to the fruit on the treesof an orchard equipped with my heaters.

Having described my inventi n, I claim- 1. A heater comprising a metalpan having draft ports in the side walls; a grate' having radial barsmounted upon the top of said pan; walls forming a combustion chambermounted upon said grate; and a deflector mounted upon the walls of thecombustion chamber and spaced therefrom.

2. heater comprising a metal pan having draft ports in the side walls,said walls being at an, angle of forty-five degrees to the plane of thebottom of the pan; a grate having radial bars mounted upon the top ofsaid pan; walls forming a combustion chamber mounted upon said grate;and a conical demeezoee fiector mounted upon the combustion chamberwalls and spaced therefrom.

3. A heater comprising a casing forming a combustion chamber; a grate inthe 5 tom of said casingbot- , and a pan below said fgrate adapted .tohold a starting fuel, said pan having ports a dapted to cause the cenitralization of the flame from the starting fuel in the central portionof the combustion chamber casing.

In witness that I claim the foregoing I have hereunto subscribed my namethis 4th day of August, 1922.
